According to the latitude of Mexico and the distribution law of the world climate, we can infer its climate type; Photochemical smog is directly related to gases such as nitrogen oxides and solar radiation. This topic should be considered from the aspects of emission and accumulation of nitrogen oxides and strong solar radiation, among which basin topography and inversion temperature are the important reasons affecting the diffusion of harmful gases. The greenhouse effect will only lead to an increase in temperature, which is not directly related to this phenomenon; Cyclones will bring rainy weather and affect solar radiation. It is not feasible to ban private cars. The local area is located in the tropics and does not need heating.
